To all whom it may concern.'

Be it known that we, EDWARD H. LORENZ and KARL E. PEILER, Citizens of the United States, residing at Hartford, in the countyl carried by the traveling table of a glass shaping machine, thereby minimizing the danger of 'their continued adhesion to the molds and interfering with the continuous and eilicient operation of the machine.

This object is attained in the machine illustrated by providing a plungerk that is adapted to be brought down and pressed against the stem of the bottom valve of the successive molds as they arrive at their discharging position, and follow the travelling mold until the article is ejected therefrom; and arranging a hammer to travel with and strike the plunger one or more blows while it is pressing against the valve stem, so that the article which has been shaped in the mold will be subjected tno pressure and percussion as well as gravity for loosening it from the walls of the mold. Means are also provided for engaging the article beingV ejected from the mold in such manner as to push it sidewise or slightly tip it and thus release it from the bottom valve should it tend to adhere thereto. These mechanisms are designed to o erate in consonance with the movements o the mold carrying table so that there will `be no interference with the normal action of the machine. l

Of the. accompanying drawings Fig.. 1 shows a front elevation of a. glass pressing machine to which the present invention lis applied, the lower part of the machine in this View being cut away on plane indicated by the dotted line 1-1 on Fig. 3. Fig. 2 is a central vertical section of the machine on the plane indicated by the dotted line 2-2 on Fig. 1, looking in the direction indicated by the arrows. Fig. shows a plan of the ejecting mechanism wlth parts of the pressing machine cut. in section. Fig. 4 shows a plan looking down from the plane 4 4 on Fig. 2, of the ratchet which causes the hammer to tap the bottom valve of the mold for the purpose of loosening the shaped article from the mold if it should tend to stick therein. Fi 5 shows a plan looking down from dotted line 5--5 on Fig. 2, of the linger which isarranged to engage with a' side' of the shaped article so as to move it sidewise or to tip it and release it from the bottom valve of the mold should it adhere thereto.

In the machine illustrated the mold table l is rotatable and carries on its upper face a number of sets of molds 2 and 3.' One mold of each set opens upwardly and the other opens downwardlyy and the frame 4 v which carries each set has truiinions 5 that turn in bearing blocks 6. For inverting the molds a pinion 7 is connected with one trunnion and engaging with this pinion is a segmental rack 8 on an arm 9 which is connected with an arm 10 that has a segmental rack l1. This latter rack meshes with a straight rack 12 which has a roll 13 lengaging with a cam 14. The cam is so timed that at the proper moment through the racks and pinions the positions of the molds are reveised, that is, the upwardly opening mold after having 'a piece of glassware pressed therein, is turned over so as to open downward and the downwardly opening emptied mo-ld is turned over so as to open upward for receiving its next charge of glass.`

Each mold frame carries a vertically extending shaft 15 with an arm 16 bearing a roll 17 at its upper end and an arm 18 bearing a roll 19 at its lower end. Fastened to the upper end of each shaft is a finger 20 and fastened to the lower end of each shaft is a. finger 21. At the proper time during the travel of the mold table the rolls engage with a fixed cam in such manner as torotate the shaft and turn the finger at the bottom from under amold and turn the finger atv end of this shaft and extending under theI downwardly opening mold is a receiving platform 24 and at the lower end of the shaft is a roll 25 that travels in a fixed cam groove 26. This cam groove is so cut that the platform is raised up beneath the downwardly opening mold to receive the article `ejected therefrom; in the case illustrated the jar 27 is lowered so that the article can be removed from the machine.

In each mold is a bottom valve 29 having a'stem 30. This bottom valve is pushed downward at the proper time, after the glass has sufficiently cooled to permit ejection, to free the article from the walls of the mold and set it on the platform.

Around the lower part of the rotatable mold carrying table is an annular gear 31. Meshing with this gear is a gear 32 fastened to which is a gear 33 that engages wlth a gear 34 which is in mesh with a gear 35. The gear 35 is fastened on the hub of a cam 36 which is keyed to a vvertical shaft 37. This shaft is supported by the frame so that it can be moved vertically and also rotated. The gearing in the machine illustrated is so proportioned that the shaft turns at such speed that it makes one revolution for each mold that is brought into delivering position. The cam 36 travels on a roller 38 mounted on a stud 39 which is held in an adjustable block 40, and the shaft is pressed downward so that the cam rests on this roller by a spring 41 which is coiled about it. Fastened to the upper end of the shaft 37 is a head 42, carrying a plunger 43, whlch is pressed downwardly by a spring 44. The head also carries an angular hammer lever 45 pivoted at 45a to the head, and revolving therewith, and having a hammer head 50 which is disposed above the upper end of the plunger 43, and is drawn downwardly by a spring 51, this hammer lever being provided with a stop abutment 60 resting upon the head 42 to limit the downward movement of the hammer. A downwardly projecting arm 52 of the revolving hammer is arranged to engage with the stationary teeth 53 cut into or carried by an adjustable arm 54 which in turn is fastened to the frame or other stationary part of the machine. The arm 54 is preferably made adjustable upon its support, to swing around the axis of the shaft 37, thereby enabling the time of the hammering operation to be regulated. The arm 54 is secured in its adjusted positions by the bolt 54.

In operation, the head 42 revolves, carrying the hammer and the cushioned plunger 43, so as to carry the plunger in engaging coincidence with the valve stems 30 at and adjacent to the position where the paths .of the revolving plunger 43 and the revolving valve stems 30 intersect or cross each other. The revolving cam 36 holds. the shaft, with its h'ad 42 and plunger 43, above the plane of the mold structures, unt-il the plunger and the respective plunger stems are in engaging coincidence, at which time the stem 36 allows the rotating shaft and its head to drop, so that the plunger 43 will exert a cushioned and increasing pressure upon the upper end of the valve stem 30. The pressure of the spring 44 will ordinarily be sufficient to release and eject the piece of glassware, unless the latter adheres to its mold, in which case the plunger 43 will be pushed upwardly against the pressure of its spring 44, within the range of movement of the hammer head 50, which at that time is being vibrated by the teeth or notches 53 engaging the arm 52 of the hammer. Thus, if the article is not freely dislodged by the cushioned pressing movement, the percussive blows of the hammer upon the plunger 43 will insure the releasing and ejecting of the article, which when released drops upon the platform 24, which at that time has been brought up in position to receive it. The platform is then lowered until the glassware is clear of the mold, or to any desired level at which the ware is transferred from the platform to any suitable receiver or conveyor that may be emplo ed for transferring the finished articles o glassware tothe annealing lehrs.

To break the ossible continuing adhesion of the bottom of3 the glass article to the face of the mold valve, when the valve is pushed or hammered down, a more or less elastic finger 56 fastened to a collar 57 by a screw 58 to the frame, is arranged to project slightly into the path of the lower edge of the article as it moves along and so push it sidewise or slightly tip it. This separates the bottom of the article from the mold valve if it should adhere thereto.

This ejecting mechanism may be used with a pressing machine having a continuously rotated or intermittently rotated mold table carrying any desired number of molds. In the latter case the ejector may perform its functions between the intermissions of the table rotation. while the molds are moving` from one station to another.
